In 1854, Hassenstein began studying cartography and working under August Petermann in Gotha, founder of Petermanns Geographische Mitteilungen. Over the ensuing years, Hassenstein drew numerous maps for Petermanns Geographische Mitteilungen before relocating to Berlin in 1866 to work for another cartographer, including Karl Klaus von der Decken. He returned to Gotha two years later and works on maps for Henrich Theodor Menke's edition of Spurner's atlas of medieval history.

Johan Georg Justus Perthes (September 11, 1749 - May 2, 1816) was one of the most important German cartographic engravers of the 19th century. He was born in the Thuringian town of Rudolstadt, the son of a court physician. In 1778, he began working as a bookseller in Gotha. Perthes began his publishing empire shortly thereafter with the 1784 issue of the famed survey of European nobility known as the Almanac de Gotha. In the next year, 1785, he founded the cartographic firm of Justus Perthes Geographische Anstalt Gotha. His son Wilhelm Perthes (1793 - 1853) joined the firm in 1814. Wilhelm had prior publishing experience at the firm of Justus Perthes' nephew, Friedrich Christoph Perthes, who ran a publishing house in Hamburg. After Justus Perthes died in 1816, Wilhelm took charge and laid the groundwork for the firm to become a cartographic publishing titan. From 1817 to 1890. the Perthes firm issued thousands of maps and more than 20 different atlases. Along with the visionary editors Hermann Berghaus (1797 - 1884), Adolph Stieler (1775 - 1836), and Karl Spruner (1803 - 1892), the Perthes firm pioneered the Hand Atlas. When Wilhelm retired, management of the firm passed to his son, Bernhardt Wilhelm Perthes (1821 – 1857). Bernhardt brought on the cartographic geniuses August Heinrich Peterman (1822 - 1878) and Bruno Hassenstein (1839 - 1902). The firm was subsequently passed to a fourth generation in the form of Berhanrd Perthes (1858 – 1919), Bernhard Wilhelm's son. The firm continued in the family until 1953 when, being in East Germany, it was nationalized and run as a state-owned enterprise as VEB Hermann Haack Geographisch-Kartographische Anstalt Gotha. The Justus family, led by Joachim Justus Perthes and his son Wolf-Jürgen Perthes, relocated to Darmstadt where they founded the Justus Perthes Geographische Verlagsanstalt Darmstadt. Learn More...

August Heinrich Petermann (1822 - 1878) was a German cartographer. Petermann attended the 'Geographische Kuntschule' (Geographica School of Art), which was started by Heinrich Berghaus with the support of Alexander von Humboldt, in Potsdam beginning in 1839. Students at the school were obliged to work on many of the school's contracts, including maps for several different atlases. Following his time in Potsdam, Petermann relocated to Edinburgh and London from 1845 to 1854, where he gained insight into the commercial aspects of the cartography business. In 1854, Petermann returned to Gotha, Germany and began working with the Perthes brothers publishers. While working with the Perthes brothers, Petermann founded the journal Petermanns Geographische Mitteilungen, published from 1855 until 2014, long one of the most prominent German-language geography journals.
